A CORPORATION OF NEW JERSEY,

FASTENER-SETTING DEVICE.

Application filed September 25, 1918. Serial No. 255,680.

ting fasteners in sheet material and more specifically to machines ofthe duplex type such as are employed in setting eyelets or lacing hookssimultaneously in or near the edges of two superposed pieces ofmaterial.

In machines of the above character it is common to provide work-engagingmembers comprising a work support, and in some cases an auxiliary worksupport, for assisting the operator in presenting the material to theoperating tools, together with presser feet for holding the work withconsiderable pressure against the opposite faces of the support duringthe operation of the tools. The present invention has for one of itsobjects, the simplification of the above parts. As herein illustrated,the main work support is eliminated and the auxiliary work support iscombined with one of the presser feet to form a single unitary device.By this arrangement the mechanism has been rendered less complex,whereby the cost of manufacture is decreased and at the same time, bythe omission of the usual fixed work support located betweenindependently movable presser feet, a uniform pressure upon both piecesof material is insured and thus 1s avoided any possibility of unequalfeeding of said pieces of material such as frequently occurs in presentcommercial machines and which results in an uneven spacing of thefasteners with consequent damage to the work.

The invention also provides formounting the work-engaging members formovement relatively to each other to produce the necessary work-holdingpressure and to facilitate introduction of the work therebetween,resilient means of simple form being provided which tend to maintainsaid members in. parallel relation. 7 i

This invention also provides an mproved edge-gage for guiding the edgeof the material to regulate the distance at which the line of fastenersshall be spaced from the edge, said edge gage, the presser foot, and thecombined work support and presser foot being supported for relativeadjustment whereby the distance of the line of fasteners from the edgeof the material may be varied at will and by reason of which the normaldistance between said presser foot and the combined work support andpresser foot may be determined.

Another feature of the invention consists in an improved toolconstituting a duplex punch-anvil and set. Said tool is illustrated as adisk, the two opposite faces of which are formed to providefastenerglepching surfaces surrounding the punchec s.

Other features consist in an improved holder for said duplex tool and incertain formations of the tool and holder by which they 'are held incooperative relation to each other to provide for the substitution ofone tool for another.

Still other features of the present invention together with improvedstructural details and combinations of parts will be hereinafterdescribed at length in the specification and particularly pointed outin. the claims, reference being had to the accompanying drawings inwhich,-

1 indicates the main frame of the machine having projecting upwardlytherefrom a pair of'spaced brackets 8 and 4. 5, 7 and 6, 8 indicatepairs of bosses carried by the respective brackets at their upper andlower portions, said bosses having formed therein bearing openings inwhich are rotatably mounted a pair of parallel shafts 70, 71. Fixed tothe respective shafts 70 and 71 are a air of forwardly extending leverarms 72, 73, the free extremities of said arms carrying hammer members80, 81 adapted for imparting operative movement to the tools jhereinafter described. Any suitable mechanism, not herein shown, may beemployed. for intermittently oscillating the shafts 70, 71 in oppositedirections, wherebvto cause the hammer members 80, 81 to move towardeach other in imparting the operative movement to the tools.

"106 is ayoke-like framepivoted upon a vertical axis at the rear thereofand not shown, and provided with forwardly eXtend-' ,ing arms 108, 109,said arms being furnished at their free extremities with bosses 110, 111having bearing openings in which sleeve members 112, having enlargedheads 113, are arranged for vertical shdmgmovement. The opposed ends ofsaid members 112 shown at 117 are so formed as to )10- vide sets forclenching the fasteners in the material. Within the sleeves 112 areslidably mounted members carrying at their opposed extremities hollowpunches .123, the opposed ends 'of said punch carriers being arranged tobe actuated by the hammer members 80, 81, and to project beyond theenlarged heads 113 of said sleeves at certain times in the operation. 7

The yoke frame 106 is provided on its forward face at a pointintermediate the bosses 110, 111with an opening for the reception of abracket 201 (see Fig. said bracket being provided with a an. surface at202 for engagement by the end of a. set screw 203 (Fig. 1) threaded intoan opening in the side of the yoke frame 106 and engageable with saidsurface 202, whereby to securely fix the bracket 201 in the yoke 106.The bracket 201 provides at its free Pro extremity a flat bearingsurface 20 1. ectmg upwardly from said surface, near its lateral edges,are a pair of. pins 205, 206,

and intermediate of said pins a threaded opening 207 is'formed in saidbracket. 208 is a U-shaped frame having spaced arms 209, 210, one orboth of said arms being re silient, as herein shown the arm 209 beingrelatively rigid,the normal width of said U-shaped frame being slightlygreater than the distance between the pins 205, 206. he arms 209, 210upon their confronting faces are provided with flanges or fins 211. 212,of substantially V form in section. 213 is a combined punch anvil andset of duplex form, the opposite faces of which comprise central,upstanding bosses 214, 2141 forming 1 punch anvils, surrounding whichare clenching surfaces or sets 215, 215", this duplex punch anvil andset being substantially of the character shown in the patent to Peck,689,222,.December 17, 1901, with the exception that. in the Peck patentsuch combined anvil and set is of the single type, whereas the presentanvil and set is of duplex type. As will be noted, (Fig. 5) thiscombined anvil and set is of disc-like form, the edge portion thereofbeing provided with a circumferential groove 216.

217 is a cover plate provided with spaced apart openings 218, 219arranged for en'- gagement with the pins 205, 206, respectively.Centrally of the openings 218, 219 the cover plate is provided with anopening 220 in fins 211, 212. The disc is then moved in-' wardly betweensaid arms until it seats against the inner face of the opening betweensaid arms, the frame being slotted as at 230, if desired, in order toadd to the resiliency thereof. 7 When the discis properly seated at theinner end of the space between the arms, the free extremities of thelatter are sprung or deflected toward each other'sufliciently topermitof their being inserted between the pins 205, 206. The cover plate 217is then positioned above the extremities of said frame and in engagementwith the pins 205, 206, the bolt 221 being passed through the opening220 and screwed into the opening 207 whereby the several parts arelocked in position.

By the engagement of the fins 211, 212 with the groove 216 oftheanvildisc, the latter is held rigidly against movement in a planeperpendicular to the face of said frame, while it is held against anylateral movement in said frame by the pinching of the latter againstitssides, the long leverage provided by the arms 209, 210 permitting a veryconsiderable pressure to be brought against the sides of the disc forholding the latter in position, .a nd as the distance between said arms,when positioned between pins 205, 206,:decreases slightly from the pointof contact with the disc to the free extremities of the arms, it isevident that any movement of the disclongitudinally of the arms isprevented. The punch anvil and set is thus held in very rigid relationto the the hammer members .of the punch .carriers thereby causethepunches 123 to move from opposite directions toward the opposed anvils214, 214*.

The sets 117 also move outwardly equally with the punches at this timeby contact of the heads 113 with the hammer members but are not movedsufiiciently to contact with the opposing sets 215, 215. As the punchesmove toward the anvil disc 213, they are caused to pass into and throughthe hollow shanks of a pair of eyelets or Similar fasteners which arepresented in proper posi tion for this action either by hand or anysuitable automatic feeding mechanism such as is common in the art butnot herein disclosed. As the hammer members complete their down-strokethe punches are forced through the material and into engagement with therespective anvils, 214, 214 The yoke frame 106 is now given a lateralswing ing movement about its pivot by means of a link 134 having pivotalengagement with bosses 134, 134 projecting from the face of said frame.During such movement the ends of the punch carriers, which at this timelie substantially flush with the surfaces of the enlarged heads 113, arebrought into alignment with slots 300 in the respective hammer members80, 81. The hammers are now given a further movement toward each other,thereby moving the sleeves 112 toward anvil disc 213, and by engagementof the sets 117 carried upon the ends of said sleeves with the eyeletsencircling the punches, said eyelets are forced into the openings in thematerial and are clenched against the opposed sets 215, 215, the ends ofthe punch carriers during such further movement of projecting into theslots 300 in the latter.

During the lateral swinging motion of the yoke member 106, the punches123, are in engagement with the material which is thus fed laterallyinto the position in which the eyelets are set. After the setting of theeyelets, the hammers in being retracted cause the sleeves 112 to moveaway from each other by engagement of the forked arms 113 carried by therespective hammers with the under sides of the heads 113., whereupon theframe 106 is swung laterally to its initial position.

In order to properly hold the work during the backward swinging movementof the yoke frame, and also to position it properly during the operationof the tools, a pair of opposed work-engaging members have beenprovided. The member 251 is fixed upon an upwardly extending arm 301 ofa lever 302, the latter being pivoted at 303 upon the extremity of anoutwardly extending bracket 304. The bracket 304 comprises asubstantially cylindrical stem portion adapted to be received in asuitable opening in the machine frame wherein it may be secured by a setscrew 304 (Fig. 2) or equivalent means, the bracket thus being capableof bodily adjustment in a front-to-rear direction. 305 is a leaf springfixed to the under side of said bracket and bearing at its freeextremity at the point 306 beneath the lower sur face of the lever 302,thereby normally holding the same in the position shown in Fig. 2. Anadjusting screw 307 is provided for varying the tension of said spring.

The member 251 which serves as the upper presser foot is mounted upon anarm 301* of a lever 302 similar to the lever 302, said lever 302 beingpivoted to the front extremity of a bracket 600 substantially likebracket 304 and similarly adjustably fixed in an opening in the frame bya set screw 601. Lever 302 is acted upon by a spring 305 similar to thespring 305 and likewise adjustable. By the above arrangement it will beevident that the members 251, 251 tend to move toward one another andnormally to maintain their opposed surfaces in Contact.

The lever member 302 is provided with a sleeve 308 projecting upwardlyin alignment with the arm 301" thereof, said sleeve serving for thereception of a rod 309 freely slidable therein, the upper end of whichis pivoted upon a pin 310 projecting laterally from the face of theupper hammer 80.

The member 251 has fixed thereto or integral therewith a part 311, shownas projecting laterally and to the right thereof (see Fig. 1), said part311 serving as a work support for assisting the operator in supportingthe material as the latter is moved forwardly into contact with thework-engaging members and the operating tools. In some cases,particularly in corset work, the strip of material operated upon is ofconsiderable length and requires some support in order to maintain itproperly in alignment with the operating tools, and in previousmachines, it has been customary to employ a support directly between thetwo presser feet and against the opposite surface of which said presserfeet press the respective strips of material. It has also been common inmany cases to provide an adritional, auxiliary support at some distancefrom the main work support and over which the strips of material werepermitted to pass. In the present machine by the above arrangement. themain support has been eliminated, and the member 251 with its lateralextension 311 has been made to serve both as a presser foot andauxiliary work support, being thus in effect a combined presser foot andwork support and the sole work support in advance of the punch andsetting mechanism.-

By the elimination of the main work support, the two strips of materialbeing held directly between, the two presser foot elements arenecessarily subjected to an equal pressure, and as the two strips ofmaterial are in physical contact with each other, any movement of onetends to move the other due to the frictional engagen'ient of the two.Thus any tendency toward unequal feeding of the two strips is to a verylarge extent avoided, enabling the n achine to set the fasteners in theopposite strips of material at uniform distances apart which is anessential feature in a machine of this character.

In order to assist the operator in maintaining the materialupon the worksupport 311, a resilient holder 312 in the form of a bent spring hasbeen provided, said spring being secured to the under surface of saidsupport 311 at the point 313 and extending rearwardly and upwardly overthe edge vof said work support, and into substantial contact with itsupper surface.

500 is an edge-gage member con'iprising a work-edge contacting surface501 and a pair of forwardly projecting flanges 502, extending outwardlyfrom the upper and lower edges respectively of said surface. The member500 is provided with a cylindrical stem 50% projecting rearwardly fromthe surface 501 and arranged to be received within an opening 505(Fig. 1) in the machine frame wherein it may be adj usta bly secured bymeans of a setscre'w 506. 507 is a longitudinal slot or cleft in member500 providing for the reception of the anvil supiiorting frame 208 andwherein the latter slides during the work-feeding movement of thepunches. In consequence of this relation of the edgegage and thefranieQUS each is adapted to brace the other and they positivelymaintain their cooperative relation. For example, the element 208 iseffective to prevent the edge-gage from turning about the axisof itsshank 501 even if the set-screw 506 were loose; and when the set-screwis tight the edge-gage is effective to brace the element 208 againstflexure.

By reason of the independent adjustable mounting of the edge-gagemember, it is possible to vary the distance of the line of fastenersfrom the edge of the material.

Moreover, due to the fact that the brackets 600 and 304 are relativelyadjustable, it will be seen that the pressure between thework-contacting members 251, 9,51 may be varied. in accordance with thethickness of material to be operated upon, bodily movement of bracket600 in a front-to-rear direction tending to move member 251 towardmember 251' in swinging about pivot pin 310- i In presenting material tothe machine, the operator places an edges of the two strips 11, B, insubstantial alignment and pushes the edge gage. Duringthe operation ofthe machine, at each downward movement of the hammer 80, the presserfoot 251 is rocked about its pivot due to the engagement of the rod 309with the sleeve 308 and such rocking movement tends to feed the materialrearwardly a slight amount,-thus keeping the material at all timescorrectly positioned relatively to the edge gage and in position forproper operation of the tools thereon. The springs 305, 305 keep thework-engaging members always in contact with "the work with suflici entpressnreto maintain the work against movement except when the latter ispositively pulled 'along between said members by the lateral movement ofthe punches while in engagement with the material. 7
